Original subtitles

The unidentified aircraft is now less than 50 miles off the coast.

It's still on a course which will bring it close to this city.

Is there time to intercept it with your rocket?

No, at the rate that ship is traveling it'll be out of radar range

before we could get off the ground.

Unless it lands.

Then ground defense will handle it, Bob.

Unless Mr. Steele thinks we can help?

Yes, Larry, I do.

It's the duty of my department to handle

all matters and matters in world security,

and you're one of my executives.

I realize that your work has usually been in the interplanetary zone.

In this case I think you ought to take charge,

both on land and in the air.

Very well. I suppose the regular

defense network has already been alerted?

Yes, they're standing by until we see what that ship's going to do.

Help me on my flying suit, Bob.

I may have to get into action in a hurry.

Prepare for landing.

The unidentified aircraft has just disappeared from the radar screen

as it was passing over the Morongo Hills.

It must have landed somewhere in those hills. Probably.

I'll fly out there and try to find it.

Good, and get there quicker than the ground forces.

They picked you up on radar. The whole country is looking for you.

That was to be expected.

But if we transfer our cargo quickly,

we can get away before they locate us.

Help him with the boxes.

Get in the back with Shane.

Calling Bob. Calling Bob.

Come in, Larry.

- I just spotted their rocket taking off.

I can't possibly catch it but I'm going to

check out what happened and where it landed.

Good, keep us posted. Okay.

What's happening there?

Someone's on top of the truck I'll shake him off.

Run under those trees and knock him off.

This side door will take us right to his laboratory.

Nobody will spot us.

Very well.

What are you doing here?

I thought you were supposed to be delivering those plans--

- Yeah, I know but we got a better deal here.

What are you?

- I am Marex, a native of the planet Mars.

Perhaps not quite a human being by Earthly standards.

However I can assure you that my people are much further advanced

in intelligence and scientific achievements than you Earth men.

What are you doing here?

For some time I have been in contact

with your assistants Roth and Shane,

making arrangements for a project I'm undertaking here.

I will need your technical assistance

and the facilities of your laboratory.

- And why do you think I'm gonna help you?

- Because I'm in a position to inform your government

that you've been selling atomic secrets

to an unfriendly foreign power.

The results of such an exposure would be much more unpleasant for you

than the alternative I'm allowing.

- What is this project you're planning?

- The orbit of our planet Mars is so far from the sun

that climatic and atmospheric conditions

there are much inferior than those on Earth.

But in spite of these physical handicaps

my people have developed the means of correcting this situation.

So my mission here is to plan an H-bomb explosion

sufficiently strong to send Earth spinning out into space

and leave room for my own planet.

- That would mean the destruction of the world and everyone on it.

That need not concern you if you are safe with us on Mars.

Unless you would prefer to await the event in the Federal Penitentiary.

- I will give you a list of what is required.

And while you're obtaining these items I will go to the cave and get

the basic construction started.

- Is that the last of it? - Yes, sir.

Good. Now I have another assignment for you.

Dr. Harding has learned that the freight

shipment of the uranium will be passing through

this area today.

The train or local freight will stop at Borella Junction about 2:15.

- You and Shane will take over there. - How many men will be on it?

- I'm not sure, so you better make arrangements for additional help.

Now it won't be safe to stop to unload the uranium at the junction.

Take the train out into the hills somewhere

between the junction and Gomez Sighting.

Find a good hiding place for the uranium.

- They'll pick it up later with a truck. - Okay.

You wouldn't wanna be caught with that map on you. Burn it.

- I'll start lining things up. - Very well.

I will be in the inner cave. You can report to me by radio.

Right.

That does it, you're all set to go.

- But that ruck may be miles away by now. - Not too far.

The signal from that radio sending unit I planted in that truck

is still coming in strong.

All I have to do is fly down the beam.

So far so good. Let's see what the infrared light brings out.

- Why, it's nothing but a railroad map.

Yes, but the section between Borella Junction

and Gomez Sighting underlined.

Which means what?

It could mean something's gonna happen

there so we gotta try to find out what.

We've got a lot of country to cover so we better split up the job.

You two go to the junction, check on things there.

I'll start at Gomez Sighting and follow back up the line.

Larry!

Isn't that Bob who's on top of that freight car?

Yes

when we got here those men were stealing the train.

Bob jumped on it to try and stop them.

Any way to stop that train?

No, my key is out. They must have cut the wire

after they saw me.

There is the brake, can you fix it?

I can fix it but it'll take time.

Maybe I can catch them in the car.

Not much chance. The road only gets near the tracks in a few places.

Is that old tank working?

Yes, we just unloaded for some farmer

who's gonna make a track drive.

Maybe I can cut across country and stop that train?

You better try. If it keeps going you'll crash

it through the passenger train head on.

Tie him to that brake wheel.

Use those.

We're not gonna much luck unloading a car

with uranium with that thing chasing us.

Yeah, we better forget it. Let's make our getaway while we can.

We better jump!

That was too close for comfort.

I wonder what that was all about.

I don't know, there must be something

on that train they were planning to steal.

We'll check with the railroad company and find out.

- I'm not looking forward to this trip to Mars.

- It won't be dangerous and you'll only be there a short time.

Our controlled explosions on Mars have already been set.

As soon as the Earth's orbit is clear

we'll move Mars in to occupy it,

then we can enjoy the same atmosphere

and climate on Mars that you now have here.

Our immediate problem is to find a safe place to land the rocket load

of electronic equipment that I have to bring in from my island base.

That cart that we find uranium

was the only thing on the train of any unusual value.

That's probably what they're after. We still can't take any chances.

Larry Martin's office. Yes, he's here. It's for you, Mr. Steele.

Steele speaking. Yes? Yes. Very well.

They just picked up an unidentified aircraft coming in again.

It's still a long way off and you may have a chance to intercept it.

I'll fly out the rocket and try it.

- Vehicle all set? - Yes, sir we got your orders.

Good.

- Hiya, Larry. We're all set. - Good, let's go.

- Fire pilot jet. - Fire pilot jet.

Calling Larry Martin's office.

Larry Martin, calling Mr. Steele.

- Hey, Larry, where are you? - We've just taken off.

Is that other ship still on radar?

We lost them behind the map at the back of Lake Emerald.

It may have landed there, you better check them.

Yes, sir.

Heading for Lake Emerald.

Here it comes.

I can't see any sign of them

but you could hide a squadron under those trees.

We'll just cruise around a while to see if we can pick up something.

Right.

- That's all, I'm taking off at once. - Okay.

There he is. They're just taking off.

We take after them?

Yes, but don't follow him too close.

All we wanna do is find out where he's going.

- We under control? - Just barely. Fuel pressure is dropping.

Must have cracked a line.

We can't keep up with him now and we can't maneuver to get a shot at him.

Let's head back to field. - Okay.

So now our next move is try to find out

what that rocket ship was doing up there in the lake.

- You didn't see any sign of a truck this time, did you?

No. There were no roads near the place where it landed,

but it was close to the lake.

If they unloaded anything it could be picked up by boat.

There are a lot of boats on that lake.

- Yes, and we gotta check them all, so let's go.

You two take one side of the lake, I'll take the other.

There's somebody snooping around our stuff.

Well that's all we salvaged from the wreck of the speedboat.

What is it?

Well it's part of an electronic device

but I've never seen one just like it before.

Neither have I.

But it's certainly for some illegal project

or they wouldn't be smuggling it by rocket ship.

That's a reasonable guess but it still doesn't tell us just what it is.

No but I think I know who can tell us.

Dr. Harding.

Yes, he's done a lot of research in electronics,

but he never seem to be willing to work with anyone else.

I know he has reputation for being very secretive

but I have the authority to demand his cooperation.

Let's box this up and take it out to him.

Well we have enough material here to keep going for a while.

Fortunately my island base can replace the parts that were lost.

How about getting it here? They'll be watching for the rocket from now on.

The country which was trying to buy

my atomic power plant designs is still on the market.

They would probably let us use one of their submarines,

if we were willing to give them the designs.

There go the man who picked up that stuff from the rocket.

What can I do for you?

We wanna charter a boat. Just an open job, about 25 feet, but fast.

- When do you want it? - One week from tonight.

We won't need it for more than a couple of hours.

I don't know, I'll show you what I've got.

You're under arrest.

Search them, Bob.

Ever see those two before?

- No, but I sure like to see them again. - I'm afraid they won't be back here.

But we do know they got business in the harbor a week from tonight.

And we'll be on hand to see what takes place.

Nothing in sight yet.

No, but we better keep looking.

- It's about time that sub showed up, isn't it?

Yeah, but you won't see it.

Even the boat will stamp up the buoys.

Hey, what's that boat doing?

They're bringing up something out of the water.

Hey, there's a boat heading this way.

We won't have time to pick up that other buoy, sink it.

I want that buoy. Stand by to pick it up.

Stop them!

Throw that net over in front of them.

That net fault our prop up good.

If we can clear that prop and get to my car in time

we can still catch them.

Let's get to work.

Try toward the canning wharf.

If you see any sign of them, call me on the radio.

Right.

Calling Larry, calling Larry.

Come in, Bob.

They're heading north along Front Street in a black panel truck.

You want me to follow them?

- No I'll take over now. - Okay.

Pull over and stop.

Pull over and stop.

It's my guess that some enemy power

is preparing to build A-bombs right here in this country.

And then use them here?

Afraid that may be it. We must use every means we can to stop them.

Well one thing the authorities should check up

on all the supplies and material

and equipment of this country that might be used for atomic devices.

All such supplies are under strict government control already.

We'll ask the government authorities to recheck their security measures.

Let me know if you find anything suspicious.

Well, Larry.

Yes, Ross has already removed the Uranium from the mine.

All you have to do is to meet him with the plan at the usual place.

Are you sure you can trust Ross from the men with the plane?

I don't like letting strangers in on our projects.

They don't know anything about your plan to blast Earth out of its orbit

so Mars can take its place.

All right, Mr. Steele, we leave right now.

It looks like the security controls

aren't as tight as Mr. Steele thought they were.

The King Pin Mayan reports a shipment of high grade

uranium ore stolen.

Stolen from the mine?

Yes, apparently it was loaded on the pack horses

and taken out across the desert.

They tried to follow the tracks but they lost it in rocky grounds.

So we gotta make a couple of Indians and trail them.

Do I have to ride a horse?

No, but you may have to do some scrambling around on foot.

You follow this path. I will fly over those hills in the west.

- We'll keep in touch by radio. - Right.

Okay boys, there they are.

Calling Bob, come in, Bob.

Come in, Larry.

I've spotted them. They're loading the stuff on a plane

on a dry lake about a mile west of where you are now.

Drive cross country until I meet you.

Right.

We'll get in as close as we can before we open up on them.

- Right. I brought these along. - Let's go.

Take off as fast as you can.

- Hey, they're taking off. - These will stop them.

That did it.

Yeah, there won't be much fight left in that crew now.

Calling Sue, calling Sue.

Yes, Larry, come in?

We recovered the Uranium.

They were transporting it from the pack horses to a plane.

We disabled the plane and have captured the two men in it.

But the others escaped.

Do you have any idea who they were?

Yes. One of the prisoners talked. The leader was a mine foreman named Ross.

I don't expect him to go back to the mine now but he had an

appointment to meet two pay off men this afternoon.

So I'm going to the mine and look for them. Is Mr. Steele still there?

Yes.

Ask him to phone the mine superintendent

and arrange for me to get in.

I'll take care of it right away.

You make all the arrangements. Good luck.

Ross is supposed to be working down the lower level.

There must be a shaft somewhere ahead.

Hold it. I thought you folks might show up here.

This is very serious.

We must have Uranium for the construction of our H-bomb.

Is there another source or supply?

I know where I can obtain some but the cost would be very high.

And since we've lost the money we paid to Ross

I'm afraid we can't afford them.

That isn't problem. Many of your banks are loaded with cash.

They're loaded with guards too.

Your part will be very minor and perfectly safe.

On Mars we long ago learned to use mechanical devices

for difficult or dangerous work.

You mean you could build a machine to rob the bank?

That's what the mouse do.

Only you would call it a robot.

A mechanical man whose movements we can control

from a panel here in this laboratory.

- Do we have the necessary material here to build one?

We can buy the necessary electronic parts

and any sheet metal shop can construct the body for us.

Well, we will need...

Calling M, calling M.

Yes, Roth?

- We're all set. - Very well I'll take over from here.

The cops will be here in a minute, hurry up!

- Calling Car 16, calling car 1 -6.

Go to the Perennial Bank. Alarm ringing.

Get going.

They're all right now.

They're robbing banks too?

Yes, Sue, it's the same gang all right.

The police traced the getaway car through town

but they lost them somewhere in the Morongo Hills.

Why that's where that rocket landed the first time.

Right. So there's a chance they might have headed for the same cave.

I'm going to have a look.

Be careful.

You sure that box is water tight?

Absolutely.

I'll radio Marex that you've arrived safely.

You better wait to see if he has any further orders.

Okay.

Get your hands up.

Turn around.

Calling Marex, calling Marex.

Come in Narab.

Roth and Shane got here with the money,

but someone has just captured them

at the outer cave.

- Is the robot still there? - Yes.

Then I'll take over.

Go over that wall.

Now to finish him.

- There's an axon the box right behind him. - Yeah, that'll do it.

His master control's on the robot.

Calling Bob, calling Bob.

Come in, Larry.

The gang came to the cave all right.

They got away but I've got the robot and the money must be here somewhere.

But if Larry Martin investigates that underwater tunnel.

Don't worry about Larry Martin.

We now have a sure method of eliminating him.

The robot is in his laboratory.

Tonight you and Roth will break in there and then repair it.

Then stand by the controls.

And the next time Martin enters his laboratory

send the robot into action.

And that should solve our problem.

Shane, you will take me out to the cave now.

We must be on guard in case Martin

returns there before you have a chance

to get the robot working again.

Well, everything seems to be in perfect working order.

Larry Martin is due for a very unpleasant surprise tomorrow.

- Morning, Sue. - Morning.

- Hiya, Bob. - Hi.

Everything ready?

Yes, there's the diving helmet and the underwater line.

Seems all right.

You got plenty of oxygen?

I think so, we will take along an extra tank.

Look out!

Throw the main switch.

We were lucky that time but I'll not take any more chances.

While Bob and I are out the keep

you take that thing apart in a lot of little pieces.

Right.

It's no use. I'll warn Marex.

Calling Marex. Calling Marex.

Come in, Harding.

The Robot attack failed. Larry Martin disabled it.

That means Martin will be coming to search this cave at any time.

Tell Roth and Shane to come out here immediately.

- Do we have any explosives that can be detonated under water?

Yes. Some of our small TNT bombs will do.

Then get one ready at once. We must set up a booby trap in the shed.

Yes, sir.

Let's rig this light.

Put them up.

Looks like that blast got Martin, let's go.

What happened down there?

It must have been a booby trap.

I fell in something and everything went black.

We'll try to get a map of this mine from the former owner.

If it shows any working back up here we'll do more investigating.

Okay. But we probably scared them out of ever using this place again.

Calling Dr. Harding. Calling Dr. Harding.

So you can make your arrangements to purchasing the uranium at once.

In the mean time we must have the other materials

for the nuclear reactor brought in from the island base.

Yes, but try to find a better method

of bringing the cargo ashore this time.

The material you'll be handling is radioactive enough to cause

considerable electrical disturbance.

So get it into your lead safe as quickly as possible.

Yes, sir.

Calling X71. Calling X71.

Having any trouble?

Not a bit. I just lowered the nets in the dire

when the submarine put this stuff in.

Is this all of it?

No, I'll get the rest tomorrow night.

Okay. Help us get this stuff in the truck.

Just after one o'clock this morning there was violent interference

interference with all radioactivity in this area,

from the waterfront to the east side of town.

It was undoubtedly caused by some

highly radioactive material being moved to that area.

This does not necessarily tie in with

that gang you've been having trouble with.

But it does indicate illegal traffic in some atomic material.

- We know that gang's been working on some sort of atomic project.

Yes, and we know they've been trying to smuggle material to this country

so it adds up.

I'll fly over the harbor area with a radioactivity detector

and try to locate the source of that interference.

Calling Bob. Calling Bob.

Yes, Larry?

I picked up a strong reading right over the middle of the harbor.

There are no ships anywhere near.

It's that submarine again.

That's my guess.

So I want you to charter a speedboat, get an underwater detector

and some small depth charges.

Right. I'll meet you here at the lab when you get back.

Everything set for tonight.

The gear will all be put in the boat by dark.

Good. Can I go with you this time?

I'd rather have you patrol the waterfront area with a geiger counter in case

they get the stuff ashore before we locate it.

I picked up something.

- Submerge to 100 feet. - Aye aye, sir.

Reduce to quarter speed.

We're right over them. Hold her steady.

Submerge another 100 feet!

Missed it.

What's she doing here?

She must have picked up that stuff on this geiger counter.

Take her up there and tie her up.

That's the last one. Hey.

Let's get out of sight.

Hold it.

Search them.

Can you find any trace of the rest of the cargo?

No, it's disappeared completely.

But if they try to move it again we'll be ready for them.

I have men with geiger counters planted on all the main highways.

If anything radioactive is moved out of town we'll pick it up.

That's a sensible plan. You know that guy is using

atomic material,

so you have a good chance of getting on that trail. Check with you later.

So all the equipment is safe in my vault

That is very serious loss and will be difficult to replace.

But in the mean time we can go into the other phases on our project.

Have you arranged to get a supply of uranium?

I've arrangements to Roth to take the place

of the guard on a truck load of uranium

leaving the chemical warehouse this afternoon.

Good.

Once we get that uranium we can go

into the final stages on construction of the bomb.

Stay here. I'll signal you when it's clear.

Okay.

I'm your new guard. Sorry I didn't get here in time to check the load.

Well it looks okay to me, but you can give it a quick count.

All right.

This is a stick up.

Pull over.

Good. We'll get right after it.

Our spotters picked up a radioactive truck

heading east on Highway 40 just out of Kelson.

Bob, take your car and get on that highway.

Right.

Sue, you stay here. And both of you keep your radios open.

I'll let you know if I need help.

Calling Bob and Sue. Calling Bob and Sue.

Yes, Larry?

Come in, Larry.

I picked up a hot reaction from a truck going east

on Highway 40 almost to the foot of the pass.

Where are you, Bob?

- Just a few miles behind it. - Then catch up with us as soon as you can.

I'm going to board the truck. I'll leave my radio open

so you can both hear what happens.

- Okay. - Right.

Stay where you are.

Hey, Roth. Larry Martin just landed in here.

Hey Shane.

This roadster back there looks like he's tailing us. Take a look.

Okay.

You can relax now, Roth. I stopped him.

Good.

There ought to be a phone both at that gas station.

I'll make a call.

He says to use Martin to get into his lab

then we can grab that electronic gadget they got from us.

Good idea.

Did you hear that, Sue?

Yes.

There's a revolver in the second drawer of my desk.

- Can you use it? - Of course. I'll be ready.

Just walk right on in. Don't make any brakes. There's two guns behind you.

Stay here till we see it's okay. Go on.

Keep him covered. Here's what we want.

Now that fixes him. Get that instrument and let's go.

Larry, I thought they'd killed you.

- Have they gone? - Yes.

So now we have everything we need to complete the H-bomb

except the detonator which is still on the island.

- That's radioactive too, isn't it? - Of course, why?

It's obvious that Larry Martin has been tracing our recent shipments

with radioactive detectors.

By now he undoubtedly has a screen

which will be very difficult to penetrate.

Yes, you're right. It would be too risky to move it through town.

We'll have to use the spaceship.

We can bomb it tomorrow and rocket before it has time to take off.

Can you secure some aerial bombs?

Yes, I have several experimental ones here.

We must create those bombs and haul them out of here at once.

Then arrange for a boat for tomorrow.

Okay, but you wanna get rid of that truck.

It's sure hot now.

Very well. Arrange to get another one.

But take the old one away from here.

Okay. Go to town and pick up another truck.

I'll meet you out in the canyon,

we'll transfer this stuff and we'll leave the old truck there.

This is a portable radio transmitter, the kind they use on life rafts.

It puts out a constant signal,

one that can be picked up in a directional receiver

anywhere within 100 miles.

If I find that truck I'll plant this transmitter on it.

You stay here until I get back then we'll start using the small receiver.

Hey, there's Martin.

Hey, if he hits one of these bombs.

Yeah, you're right. Get the engine started, I'll keep him covered.

I was glad they ran for it.

I'm just hoping they take that truck to the headquarters

so we can nail the whole gang.

The direction the signal is coming in strong.

The truck's due west of here now.

Stand by the radio, Sue, we'll keep you posted.

Let's go.

Take the next turn right.

Looks like we're heading for the water front.

Hey!

What's this?

It's a radio signal transmitter.

No wonder Martin let us get away so easy. He's tailing us.

Take the truck and get going,

anywhere to lead him away from here, I'll handle the boat.

We'll have to turn... - Hey!

That looks like one of them now.

Put me alongside it.

All right, we'll be there, thanks.

It looks like Mr. Steele's campaign to learn anybody

handling atomic supplies is paying off.

That was a dealer in electronic equipment

who reports a couple of strangers asking for some special tools.

- Did he give it to them? - Not yet.

He said he'd have the stuff for them in an hour.

That'll give us time to get on there and look them over.

Right on the minute.

That's the store just ahead and we'll wait here.

There they are. Our two old pals.

- Right. This is our chance to follow them to their headquarters.

- You suppose that's their hideout? - Could be.

Looks like they're getting ready to load something in the car.

Hey, it's Martin.

Get the car started, I'll keep them busy.

Shall we follow them?

Larry Martin is sure to intercept our rocket if we try to bring it in.

But we must.

We have to get that detonator from the island

to complete our hydrogen bomb.

Martin's rocket must be destroyed.

It'll be a tough job, it's well guarded.

That ray gun you developed,

would one of its shells penetrate the hull of Martin's rocket?

Yes, it would go through the hull and burst inside.

The that's our answer.

When martin takes off to intercept our rocket

he will have to fly over Eagle Peak.

You and Shane set the gas gun up there, blast him when he comes over.

Okay, when will your rocket be coming through?

- As soon as you get the canon set up I'll radio them to start.

Okay.

What's up now, Larry?

That mysterious rocket is headed this way again.

I've ordered Dick to take off my ship and I'll fly aboard it.

Be careful.

- How are you doing, Dick? - Everything's fine. What's the course?

Hold her as she goes. I'll see if I can pick up something in radar.

All right.

Let 'em have it.

What's that?

It's fire bomb. Or gas!

- That's it, Dick, let's head back. - Right.

Here's the detonator.

Elah said he'd stay in the rocket.

Is the rocket well hidden?

Yes, we covered it branches. Nobody can spot it from the air.

Good. Nothing can stop us now.

It'll only take a few hours to attach this detonator

then we can all take off for Mars.

Are you sure the rocket can carry all of us

and your men from the island too?

Oh yes. Now get Dr. Harding.

He's going to help me make the final adjustments on the bomb.

Okay.

- It's putting out a strong transmission wave.

But that means it's televising a picture

of this room right to its control board.

Which is exactly what we want.

My indicator will keep me on the beam

and I'll fly right along at the gang's headquarters.

If they have their receivers on

they'd be waiting for you with a warm welcome.

That's a chance we'll have to take.

Stand by the radio, I'll keep you posted.

Calling Bob. Calling Bob.

Yes, Larry?

I'm at the end of the beam and it's Dr. Harding's house.

What, you mean Dr. Harding is one of that gang?

It looks like it. The robot control panel is certainly in his house

but it'll take some strong evidence to convict a man like Dr. Harding.

Finding the control panel at his house

Not unless we prove his panel actually controls the robot.

So load that robot in the car and bring it out here as fast as you can.

I'm going inside now but I'll keep my radio open

so that you'll know what's going on.

Right.

- What are these men doing here, Dr. Harding?

They're trying to steal some of my designs.

They forced me to put them in this briefcase.

Turn around.

Stay where you are.

Good work, Doc.

Got any diving gear? You'll need to go in through that water tunnel.

Yes, in that cabinet, there are two of them there.

What happened?

They knocked me out. Did you hear anything after that?

Yeah, just before they left they were talking about taking some diving gear

to go through the underwater tunnel.

Then there is a tunnel out of that shaft in the cave?

There must be, we better get out there...

Wait a minute. You've got the robot in the car.

We've got the control panel here.

We'll take it along and let the robot do the fighting for us as well.

Hey,

we'll take that diving gear too.

All set?

There he goes.

That's that.

We'll leave the robot there and try that underwater tunnel.

Let's get the diving gear.

Turn on the air.

We couldn't find anything down there the last time.

Maybe I didn't look close enough.

There may be some kind of a concealed door.

It's Larry Martin.

Take care of them.

There, everything's completed. The bomb will explode in two hours.

By that time we'll be well on our way to Mars.

What did you find down there?

There's a shaft to the back end of that tunnel. What can we do about it?

We can keep them in there until we get help.

Go out in the car and radio Mr. Steele

to send some troops with underwater gear.

We're trapped.

No we're not. Where are those gas bombs?

- They're right over there, sir. - Get them.

We can shut off that bomb and give ourselves up.

Do you think I'm going to abandon our whole project

just when we're on the verge of success?

My life means to more to me than your project.

I'll shut off that bomb myself!

It'll be another hour before they get here.

- Maybe we can catch them. - I better fly after them.

Prepare to take off at once.

Calling Sue. Calling Sue.

Come in, Larry.

That rocket just took off in the mountains back at Lake Emerald.

Tell Dick to take off with my rocket at once. I'll board it in the air.

Right.

How are you, Larry? Where do we go now?

Just hold her as she goes until I pick up that rocket on radar.

Right.

There he is.

Firing Ray Gun.

That did it, he's going down.

Swell. Are we following?

That's rough country to land in.

I'll fly down. You take this ship back to the field.

Yes, sir.

How about the others?

I think they're all dead.

You're in pretty bad shape yourself.

Take it easy and I'll call for an ambulance.

No! First you must stop the bomb.

What bomb?

The back cave through the water tunnel.

It'll blow up soon destroy the whole world.

How can I get in there?

Turn the right knob at the left wall.

Just ahead of the trap door. Hurry!

- That zombie has a fair chance of recovery

but he's still too weak to talk.

Then we'll have to wait before we find out what this is all about.

Not entirely.

The papers we found in Harding's laboratory

explain why they're building the hydrogen bomb.

Its explosion was intended to deflect the rotation of the Earth enough

to send it out of its orbit and spinning off into space.

Those zombies must have been as crazy as they looked.

It may sound ridiculous but it's theoretically possible.

It's certainly lucky you managed to stop them in time.

Yeah, we're safe now for the time being.

But there are undoubtedly more of those

power mad creatures loose in other planets,

so it'll take constant vigilance on our part

to ensure the safety of this world.
